Ah, the joy of another Monday morning environmental heart-starter, delivered this time by the BBC News website. In this case it's a column from former oil company boss, and the possessor of most spectacular name-and-eyebrows combo I've ever seen, Sir Mark Moody-Stuart (right), who reckons that anything incapable of doing 35mpg should be banned.

Debate on this kind of thing is all to the good. But I'm wondering why I'm being lectured by a man who previously ran Shell, one of the world's largest oil companies.

Sir Mark boasts that he drives a hybrid. For which, congratulations (although I bet I could better his mpg in a Kia Ceed diesel), but he singularly fails to mention how many times he travelled the globe using Shell's spectacular fleet of corporate jets  (which includes two Falcon 900 EXs if you're interested - the sort of air-going equivalent of a Rolls-Royce Phantom). I doubt he was breaking the 35mpg barrier during too many of these trips.

More recently he's moved on to become chairman of Anglo-American, one of the world's biggest mining concerns. And, weekend-hybrid-driving aside, I'm imagining that is backside is likely still very well acquainted by the soft embrace of the generously upholstered seats in the company's Citation V and Gulfstream IV.
